Maya 2016 Ext 2 added a much needed overhaul of the BlendShape and Pose Space Deformation (PSD) workflows for technical artists and riggers. The Shape Editor in Maya offers a new Shape Authoring workflow. You can now art-direct rigs using new pose space deformation tools.
The BlendShape user interface has also been updated, and a new Blend Shape Deformer has been added, one that works more precise, and is easier to use. Here Autodesk’s Steven Roselle shows off some the new Blend Shape and PSD workflows with the Shape Editor.
Although Pose Space Deformation has been around in the form of 3rd party tools for a long while, this is the first instance of a Maya-native PSD workflow.
